Hi, my mi band 4 arrived today. Its the chineese version. My phone's (Mi 8) language is polish, when i connected my band to the mi fit app, it updated and it was still chineese. When i changed my phone's language to english, the band changed to english too. I'd like to keep it in english language, but when i change my phone's language back to polish the band immediately comes back to chineese language. What's the matter?
